Cartilage serves as a shock absorber for the human body, lubricating joints and helping them move smoothly. Its texture is softer than bone—yet stiffer and stronger than muscle. When it is damaged, patients can experience ...

Stroke and spinal cord injury patients often require gait rehabilitation to regain the ability to walk or to help strengthen their muscles. Wearable "robot-assisted training" is quickly emerging as a method that helps improve ...

Research from the University of Sussex suggests that humans are unique among primates in being able to intentionally alter the frequencies of our voices to sound larger or smaller than we really are, a capacity that is likely ...

Scientists at Baylor College of Medicine, the National Institutes of Health and Virginia Tech Carilion Research Institute have discovered a new mechanism in the mouse brain that regulates obesity. The study, which appears ...

In a developing embryo, some cells can self-segregate – like oil separating out of water – to help create the tissues and organs of the human body. For example, brain cells separate into clusters that give rise to different ...

Several peptides have an antibacterial effect - but they are broken down in the human body too quickly to exert this effect. Empa researchers have now succeeded in encasing peptides in a protective coat, which could prolong ...

New research by scientists from the University of Chicago demonstrates that the enzyme ALKBH1 can remove molecular modifications from transfer RNA, causing a measurable effect on protein translation in the cell. The study, ...

It is known that the human body can generate mechanical vibrations at very low frequencies, so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats, respiratory movements, ...

A new lab-on-a-chip system, developed by the University of Twente in The Netherlands, is capable of fast analysis of the effects of toxic substances on hemoglobin, for example. It mimicks human metabolism.

Human body

The human body is the entire structure of a human organism, and consists of a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 10 trillion cells, the basic unit of life. Groups of cells combine and work in tandem to form tissue, which combines to form organs, which work together to form organ systems.
